Niue, a tiny Pacific island nation, is a coral speck with Alofi as its capital, dubbed the “Rock of Polynesia” for its rugged cliffs and whale-filled seas. Known for coconuts, diving, and one of the world’s smallest populations (1,600), its economy relies on aid, tourism, and selling domain names (.nu). Its laid-back Polynesian vibe charms. Niue’s solitude is its strength.
